Description
PURE screw caps are laboratory screw caps manufactured from PFA with a GL 45 thread, intended for secure closure of compatible bottles and vessels used in analytical work. Offered in a pack of 5 pieces and with a pack weight of 0,218 kg, they provide a ready set of closures for routine exchange or stocking beside preparation benches. PFA construction is selected where chemical resistance and clean handling of samples matter, including environments associated with spectroscopy and spectrometry consumables. These caps from manufacturer DWK Life Sciences fit GL 45 neck systems commonly found on laboratory bottles employed in sample storage, reagent handling, and instrument-related preparation for techniques such as AAS, ICP, UV-VIS, and FT-IR. Using matched PURE screw caps helps maintain consistent sealing practice across multiple vessels in shared analytical workflows. The five-unit pack supports laboratories that prefer small replenishment quantities rather than bulk closures. Within applications focused on spectroscopy consumables, GL 45 PFA caps form a practical accessory alongside bottles and other sample-contact components used in daily laboratory operations.

Questions about PURE screw caps, made of PFA, GL 45, 5 unit(s)
What is this article?
PURE screw caps, made of PFA, GL 45, 5 unit(s) is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Plastic bottles (narrow & wide mouth), inside Bottles & containers, in Labware.
A plastic bottle is polyethylene, polypropylene or a fluoropolymer, narrow-mouth for pouring or wide-mouth for powders. It is the choice when the bottle must not shatter, and it is the wrong choice for solvents that swell the plastic.
A laboratory bottle is a closed container with a stated volume and a neck that takes a cap, a stopper or a dispenser. Borosilicate glass is the choice when the liquid is a solvent, or when the bottle will be heated or autoclaved. Polyethylene and polypropylene are the choice when the bottle must not shatter, or when hydrofluoric acid would attack glass. A narrow mouth pours. A wide mouth is for powders and for reaching the bottom. Laboratory ware of this kind is indexed under ISO laboratory glassware. Traceable volume sits with the BIPM and NIST Physical Measurement.
